Using Smart Card with C#

I was looking for a way to use GemPlus 433 Smart card reader through C# and thought it shouldn't be hard to find some samples... after security these days is a main business issue to all of us.

well i was wrong ! GemPlus has an sdk at their site but this sdk doesn't have any samples in .net all they have are C samples which didn't have much documentation. 

I needed more... so after a long search I came up with a sample on GotDotNet : C# Windows Form Demonstrating SmartCards Using PC/SC which was OK but I really needed some more functionality and didn't want to invent everything from the start interoping WinScard ...

I've noticed in one of the forums on GotDotNet an invitation to evaluate a Smart Card framework for managed .NET applications I thought to my self well... what do i have to loose... and sent this guy a letter... In return I got a full working component for evaluation purposes and.... Its a life saver !

Andreas Selle had implemented a great framework for working with Smart Cards using C# and it comes even with sample code !

Highly recommended solution for working with smart cards !

Update: Andreas just published version 2.0 of the framework !
             you can download an evaluation version over here

Update: Andreas just published version 3.0 of the framework
The following major features have been added:

* Special support for SLE 4418, SLE 4428, SLE 4432, SLE 4442, and compatible memory cards with many card readers. For example: Reiner SCT cyberJack (through PC/SC and CT-API); Various SCM Readers (through MCard API), all MKT

(CT-API) compliant readers, Athena ASEDrive III (through PC/SC) and many others.

* Special support for ACR 80 reader from Advanced Card Systems Ltd. based on ACR80.DLL.

* Special support for memory card access through the SCM Microsystems Inc.

MCard API.

* Framework enhanced to standardize and ease development of card services. A standard card service should now derived from the CardHandle class. The CardCriteria are then used to hook up a card service with its card. A source code example of a simple card service is provided by the modified Taschenkartenleser example. More examples will be provided in a future release.

* The CardTerminalConfigurator was enhanced to support configuration of ACR 80 card readers and enable usage of MCARD API with SCM PC/SC card readers.

We are dealing a lot with smart cards, and it's really nice to know there is a managed framework for that. We've just started to plan our migration path to .NET (from plain old ASP...), and I hope it'll help shorten our dev time.
Alas' Looks like the site is Offline...

BTW - welcome! Looks like we the Israelis are becoming a critical mass in the blogsphere.

Hi,

thanks for the recommendation.

Today I released version 2.0 of the SmartCard Subsembly. An evaluation version can now be downloaded straight from the homepage.

Note:

Andreas' Framework is great and he supports his software very well and with strong knowledge.
I would heartily reccomend.

I have just started to deal with smart cards 4 days ago. I wanted to use them with c#.net and I think I found the exact solution "Subsembly". I downloaded the evaluation version. I wonder if there are more sample source codes in licenced version.???

Andreas Selle said:

I just released the new Version 4.0 of the Subsembly SmartCard API. In addition I launched a new homepage fully dedicated to the product at http://www.smartcard-api.com/

The new version can now also be used from within the Internet Explorer and thus be deployed with an ASP.NET solution.

Hi all,

Whether Subsembly SmartCard API can be used for read and write operation with contactless cards like mifare 1k and 4k.

Why the sample (http://www.smartcard-api.com/)program can't detect SLE 4428 card?

Can any help me?

Cory said:

This doesn't appear to work with SLE4442 either. Keen to license it but doesn't work... or does it?
